 Time APB – user cannot repeatedly use his ID for defined time

 Zone APB – user cannot repeatedly enter an area, where he is already present

The Antipassback function is used only for the users, whose access is driven by a time

schedule. The users with access always granted are not affected by the Antipassback

function.

The Antipassback flags for an ID can be reset by inserting the ID again with use of the

programming cards (offline solution). All Antipassback flags are also reset whenever new

access rights data are downloaded from the program.

Both Zone and Time Antipassback flags are written either immediately after an ID is read,

or after relevant door is opened (relevant input is disconnected).

6.9.1 Time Antipassback

The Time Antipassback is defined by the ABP timer initial value (in minutes), which is set to

the ID after passing at the reader module. If the users uses the ID at the address during the

timer for the ID is running, the Time APB alarm is raised. Following parameters affect the

Time APB function:

 APB timer initial value – defines the Time APB flag (timer) value set to the ID after

passing at the reader module. If a user uses the ID again before the timer elapses,

Time APB alarm is raised.

 Open door after APB time alarm – if the option is enabled, the Door open function is

performed after the Time APB alarm is raised.

6.9.2 Zone Antipassback

The Zone Antipassback is defined by enabling the option for the relevant address. The

Zone APB flag is set for the ID when passing at the reader module. If a user uses the ID

again when the Zone APB flag is set, the Zone APB alarm is raised. Following parameters

affect the Zone APB function:

 Enabled – enable/disable general Zone APB flag setting.

 Enable in offline mode – if the option is not set, the module operates in offline mode

like if the APB function was not implemented.

 Open door after APB Zone alarm – if the option is enabled, the Door open function is

performed after the Zone APB alarm is raised.

6.10 Disabling function

This function is implemented since the FW version 5.08.

The module disabling function can be set at the second input. The logic of the function is

configurable. The module behavior is as described below when the disabling function is

active:

 User with access driven by a time schedule cannot run the door open function

 User with access always granted is not affected by the disabling function

 Remote door open function cannot be performed

 Remote identification with ID is disabled for users with access driven by a time

schedule
